width and height or layers. Ndarrays use theshapeattribute to return a tuple (an ordered sequence of numbers) stipulating the dimensions of the array. The data type used in the array is specified through thedtypeattribute assigned to the array. These can include integers, strings, floating-poin...
In this case, you have to handle some missing values that are indicated by the 'MISSING' strings. Since the genfromtxt() function converts character strings in numeric columns to nan, you can convert these values to other ones by specifying the filling_values argument. In this case, you ...
